At this point the best course of action would be to put a scope on the crank and cams signals to verify them. Also, remove your engine grounds, clean then, and reinstall. Verify good clean ground to ECU. You might consider adding temporary additional grounds from chassis to engine and from battery to chassis. Bottom line is verify clean solid grounds everywhere, and if that does not work, look into getting a scope to verify those sensor signals.

The ecu looks fine but i'm guessing this may be the issue. I'm at the end of the road with the car.
